* rt2x00: do not drop usb dev reference counter on suspendStanislaw Gruszka2011-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When hibernating ->resume may not be called by usb core, but disconnect and probe instead, so we do not increase the counter after decreasing it in ->supend. As a result we free memory early, and get crash when unplugging usb dongle.

| * rt2x00: Implement tx_frames_pending mac80211 callback function.Gertjan van Wingerde2011-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implementing this callback function will cause mac80211 refrain from going to powersave state when there are still untransmitted TX frames in the queues. This would exactly mimic the behaviour of the legacy vendor driver which also doesn't go in powersave mode if there are still TX frames that are not transmitted. This should make powersaving and rt2x00 a better couple.

| * rt2x00: Serialize TX operations on a queue.Gertjan van Wingerde2011-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rt2x00 driver gets frequent occurrences of the following error message when operating under load: phy0 -> rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 2. This is caused by simultaneous attempts from mac80211 to send a frame via rt2x00, which are not properly serialized inside rt2x00queue_write_tx_frame, causing the second frame to fail sending with the above mentioned error message. Fix this by introducing a per-queue spinlock to serialize the TX operations on that queue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We make oldconfig every time when a new kernel arrives, but if we don't have such a device(I guess this is the most common case for a new device), the default value should be 'n' so that the kernel size we build doesn't grow up too much quickly. For anyone who has the device, it is OK for them to turn it on by themselves. Cc: "John W.

| * rt2x00: Fix transfer speed regression for USB hardwareIvo van Doorn2011-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch: rt2x00: Make rt2x00_queue_entry_for_each more flexible commit: 10e11568ca8b8a15f7478f6a4ceebabcbdba1018 introduced a severe regression on the throughput for USB hardware. It turns out that the exiting of the rt2x00queue_for_each_entry() was done too early. The exact cause for this regression is unknown, but by disabling the premature exiting of the loop seems to resolve the issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the get_antenna and set_antenna callback functions, which will allow clients to control the antenna for all non-11n hardware (Antenna handling in rt2800 is still a bit magical, so we can't use the set_antenna for those drivers yet). To best support the set_antenna callback some modifications are needed in the diversity handling. We should never look at the default antenna settings to determine if software diversity is enabled. Instead we should set the diversity flag when possible, which will allow the link_tuner to automatically pick up the tuning.
